On the SUN communityONE video they show a demo of openSolaris running on pretty beefy hardware, and the test I did in a VM (virtualbox) was definitely a hog resource-wise. My questions are regarding the CPU and RAM "requirements" of a simple openSolaris fileserver/NAS running zfs raid z1 or z2 with 5 or 6 disks and sharing via samba/cifs.
Would using a low end intel (1.8 c2d) make a difference vs a more powerful one? What about a celeron?
I heard ZFS uses lots of RAM for caching. What kind of performance difference, if any, could I expect for going from 4 to 6 GB, or from 6 to 8 GB ?
